I have a 12v 4k watt pure sine wave inverter in my truck running 12' 4awg with a 200a main line breaker, new deep cycle 1k amp 12 volt battery, 250a charging alternator with a 5f (5k watt 550a) capacitor next to the inverter (6 inches). I run it at 50% load without issue but the other day ran it...
